what is meant by interrupt vector table? what it's use?
Answer Posted / aarti
When 8086 responds to an interrupt,it goes to four memory locations to get the CS and IP values for the start of the interrupt service procedure. In 8086, the first 1kb of memory, from 0000H to 03FFH,is set aside as a table for storing the starting addresses of interrupt service procedures. Since 4 bytes r required to store the CS and IP values for each interrupt service procedure, the table can hold the starting addresses for up to 256 interrupt procedures... The starting address of an interrupt service procedure is called as the interrupt vector or interrupt pointer, and so the table referred to this is interrupt vector table or interrupt pointer table.

As a water tank loses heat, the temperature drops by 2 K/min when a heater is on, the system gains temperature at 4 K/min. A two-position controller has a 0.5 min control lag and a neutral zone of ± 4% of the setpoint about a setpoint of 323 K. Plot the heater temperature versus time. Find the oscillation period
